2024:10 Computational analysis of high-burnup fuel rod behaviour in PWR large-break LOCA
SSM perspective Background Quantum Technologies AB (QT) has for many years developed computational models for the thermomechanical behaviour of nuclear fuel in events such as LOCA and RIA. The research ... research projects have been based on evaluations of tests on nuclear fuel in Halden Reactor Project (HRP) and Studsvik Cladding Integrity Project (SCIP). The models developed by QT enable analyses and interpretations...

2021:01 In situ NMR condition monitoring of cable insulations in Nuclear Power Plants
SSM perspective Background As the nuclear power plants are ageing, it is important to verify that every component installed can function safely in the intended environment. Cables are among the most common ... of an accident. There is a need within the nuclear industry for methodologies which can facilitate on-site measurement for condition monitoring, while having the capability to provide non-destructive in-situ...

2007:39 Influence of Crack Morphology on Leak Before Break Margins
The way to demonstrate that LBB prevails relies on a deterministic procedure for which a leakage crack is postulated in certain sections of the pipe based on the leak detection capability of the plant. It ... large influence on the leakage flow rate and hence on the LBB- margins. SKI has therefore initiated a project to investigate the influence of the crack morphology on LBB-margins applied on pipe systems in...

2014:39 Technical Note, “Wormhole” and Multiple Loss of Buffer Safety Function Scenarios
safety functions. The “wormhole” scenario was hypothesized during the SSM Workshop on “What-if” Canister Corrosion and was based on FEP BU07 “piping and erosion of the bentonite buffer” scenario. The subsequent ... subsequent analysis found that the penetration time of the copper canister based on hypothetical size and location of the pipe is shorter than previously predicted. Note that the corrosion analysis was...
